ABSTRACT:
The ultra-thin rear projection display device described herein includes a lens system and one or more planar mirrors that are parallel to a screen on which an image is to be displayed. The screen may be a Fresnel lens having a plurality of bumps on the output surface to reduce the visibility of a stray light image. The Fresnel lens may have a diffusion layer on the output side of the Fresnel lens.
